I created a small server program from Miscro820 allen-bradley and use example project of CIP client from Siemens.,

I set up everything as described in (Getting process values via CIP with SIMATIC S7) the document. 

when I run, ii am getting Error 16#8602 ( from document - ) it is saying broken connection. By the way, i am using switch-router. From my laptop to switch, then two ethenet cable to micro820 and S-7 plc. 

I really dont know how to sovle it, i re-connect my micro820 and run it again and agian but it doesnt help.

Issue Solved: Before I used a different subnet address of two devives. That is why.. 

solution: Micro820 IP address ( 192.168.xx.xx)

              S-7 1200 ipaddress (192.168.xx.xxx)
